IMPROVEMENT lN CAR-WHEELS FOR LUBRICATING PURPOSES.

Specification forming part of Letters Patent No. 54,925, dated May '22, 1866; antedatcd May 7, 1866.

To all whom it may concern Be it known that I, JOHN W. LATOHER, of Albany, county of Albany, and State of New York, have invented a new and useful Improvement in Independent Revolving (Jar- Wheels; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation or" the same, reference being had to the annexed drawing, making a part of this specification, in which- Figure 1 is a "ertical central section of my invention, showing the oil-reservoir B, thimble-skein O, axle D, made ot round wroughtiron, collar a,and linchpin I), also showing the oil cin the reservoir B stopped in with wooden plugs d.

Gar wheels and axles constructed or made on this plan will outwear wheels having brass or composition bushings, as the surface or hole through the hub is chilled in casting, as also the periphery of the thimble-skein G, which comes in contact with the wheel in revolving, so that hardened surfaces wear against each other, thus avoiding the necessity of boring and fitting the wheel as well as the brass or composition bushing by substituting a much harder Wearing-surface.

The oil-reservoir is an annular chamber encircling the thimble-skein nearly in the middle of its length, having that portion nearest the journal contracted, as shown, to avoid too great an expenditure of w oil, as well as to give strength to the wheel. The plate 0 of the wheel springs from the crown of the oil reservoir, answering the purpose admirably of compromising the shrinkage of the wheel however unequal.

Whenever it is desirable to pour oil into the Wheel it is effected by driving the uppermost plug, '67, into the wheel, pouring the required quantityinto the aperture,and again closing the same by another similar plug. The oil should not reach a higher point when the wheel is inert thanis represented at 0, some distance below thejournal G.

What I claim as my invention,and'desire to secure by Letters Patent, is-

1. Forming an oil-reservoir, B, in the body of independent revolving car-wheels, and the oil retained therein for gradual use by means of plugs d, in combination with stationary journal 0, substantially as described.

2. Forming an oil-reservoir in such a manner as shall compromise unequal shrinkage, as shown and described.
